DC Insulator Mini
Product Description
DCÂ insulators are materials that do not allow electric current to flow freely due to tightly bound electrons. PVC (polyvinyl chloride) is a common material used for electrical insulation due to its excellent insulating properties. Insulators like this one are used to secure electrified wires and prevent arcing, power loss, or unintended connections. The threaded metal insert at the top allows for connection to other components. A103719
